摘要: 泥灰岩是一种过渡类型沉积岩,泥灰岩储层具有强烈的各向异性和非均质性,仅仅利用常规测井系列难以满足地质任务的需要。以双重孔隙解释模型为基础,通过对束鹿凹陷泥灰岩储层特征和测井响应特征的分析,总结探讨泥灰岩地层中测井系列优选原则,并分析系列优选后对解释工作的帮助及对勘探工作所起的作用。确立了泥灰岩储层评价标准,并借助成像、偶极子声波等新技术测井资料,结合实例,指出了泥灰岩地层有效储层的富集规律,对泥灰岩储层勘探及测井解释均具有一定的参考意义。

Abstract: Marlite is a transitional type of sedimentary rock, so marlite reservoir is highly anisotropic and heterogeneous. It is difficult to fulfill geologic tasks only by using of conventional logging data. Based on the dual pore interpretation model and the analysis of the marlite reservoir characteristics and logging response characteristics of Shulu Sag, the author establishes an optimum logging criterion for marlite reservoir evaluation, as well as studies on the positive effect of the optimum logging technology on the exploration and logging interpretation of marlite reservoir. What's more, a standard is established for marlite reservoir evaluation. On the basis of FMI, DSI logging technologies, this paper shows the enrichment law of effective reservoir in marlite strata, which will be a good reference for the exploration and logging interpretation of marlite reservoir

Key words: marlite reservoir, logging interpretation, enrichment law, Shulu Basin, Jizhong Depression
